ProteomicsQuantitative proteomics reveals extensive lysine ubiquitination in Arabidopsis thaliana
In this study, we describe an antibody-based approach to enrich ubiquitinated peptides from vegetative tissues for detection via peptide mass spectrometry. This enrichment method can be coupled with isobaric labeling to enable quantification from up to 18-multiplexed samples. This approach identifie...

ProteomicsUbiquitination at the Parkin ubiquitin-like domain suggests a new mechanism for Parkin activation
The mitochondrial kinase PINK1 and the cytosolic ubiquitin ligase (E3) Parkin is involved in mitochondrial quality control. PINK1, which phosphorylates ubiquitin at serine 65 residue and the ubiquitin-like (Ubl) domain of Parkin at serine 65 residue, promotes the Parkin activation and translocation ...

GenomicsThe Mediator complex subunit MED23 couples H2B mono-ubiquitination to transcriptional control and cell fate determination
The Mediator complex orchestrates multiple transcription factors with the Pol II apparatus for precise transcriptional control. However, its interplay with the surrounding chromatin remains poorly understood. Here, we analyze differential histone modifications between WT and MED23-/- (KO) cells and ...

ProteomicsComprehensive profiling of lysine ubiquitome reveals diverse functions of lysine ubiquitination in common wheat
Protein ubiquitination, which is a major post-translational modifications that occurs in eukaryotic cells, is involved in diverse biological processes. To date, large-scale profiling of the ubiquitome in common wheat has not been reported, despite its status as the major cereal crop in the world. He...

ProteomicsProtein ubiquitination in Aspergillus nidulans
Protein ubiquitination, an evolutionarily conserved post-translational modification process in eukaryotes, and plays an important role in many biological processes. Aspergillus nidulans, a model filamentous fungus, contributes to our understanding of cellular physiology, metabolism and genetics, but...

ProteomicsA COFRADIC protocol to study protein ubiquitination
We here apply the COmbined FRActional DIagonal Chromatography (COFRADIC) technology to enrich for ubiquitinated peptides and identify sites of ubiquitination by mass spectrometry. Our technology bypasses the need to ectopically overexpress tagged variants of ubiquitin and the use of sequence-biased ...

TranscriptomicsHistone H2B ubiquitylation and H3 lysine 4 methylation prevent ectopic silencing of euchromatic loci important for the cellular response to heat
In Saccharomyces cerevisiae, ubiquitylation of histone H2B signals methylation of histone H3 at lysine residues 4 (K4) and 79. These modifications occur at active genes but are believed to stabilize silent chromatin by limiting movement of silencing proteins away from heterochromatin domains. In the...

ProteomicsTwo DOT1 enzymes cooperatively mediate efficient ubiquitin-independent histone H3 lysine 76 tri-methylation in kinetoplastids
In higher eukaryotes, a single DOT1 histone H3 lysine 79 (H3K79) methyltransferase processively produces H3K79me2/me3 from me0 through histone H2B mono-ubiquitin interaction. The early-branched kinetoplastid Trypanosoma brucei harbors the essential H3K76 di-methyltransferase DOT1A and the non-essent...

ProteomicsIdentification ubiquitination of EGFR by LC-MS/MS
Previously, analysis of EGF-induced EGFR ubiquitination by mass spectrometry revealed that ubiquitinated lysine residues were located in the TKD of EGFR. However, the specific lysine residues for the CBL-mediated polyubiquitination have not been identified. To investigate the differences in EGFR ubi...
